Cows can cure HIV. Surprised? Well this is what researchers in the US have found. A study published in journal Nature by researchers at Scripps Research Institute, the International AIDS Vaccine Initiative (IAVI) and Texas A&M University has found that cows hold the clue to HIV cure. The researchers were able to induce potent antibodies against HIV in cows. Cows never get infected by HIV. Their immune systems produce unique antibodies against infections.
As part of the research, the scientists injected four calves with HIV immunogens, reports the Time.com. The researchers discovered that the cows quickly developed bNAbs, or a neutralising antibody that defends a cell from an antigen or infectious body by neutralizing any effect it has biologically, to HIV in their blood. An immunogen is any antigen capable of inducing humoral and/or cell-mediated immune response instead of immunological response.
